IMPROVBD APPARATUS FOR GHARGING SODA-WATER.

dlgs tlptule ruimt tu in tigen Entert patent rmt making part at tigt time.

Be it known that I, JOHN D. LYNDE, of Philadelphia, in the' county of Philadelphia, and State of' Pcnn- Sylvania, have invented new and useful Improvements in Generators for Making Gas for Charging Soda or Y Mineral-Waters. v

The object ofthe invention is to 'obviate the use ot' leaden linings,(which so often prove u great annoyance by getting loose and bllging) in ges-generators, and also to remedy the trouble and lessen the danger arising from the great liability of the valve between the aeidehember and the body containing the alkali getting outof order, and permitting the acid to pass through when not wanted; and I lo-hereby declare that the following is a. full, clear, and exact description of the construction 'and operation ofthe same, reference being hud-to the annexed drawings, making a part of this specification, in whieh- I Figure 1 is a perspective view.

Figure f2, a longitudinal elevation.

'A is the body or alkali-ehamber, constructed of cst iron, and lined with enamel or porcelain. It is made ot' two disks, and `ioined, withI ilanges, bolts, and pecking, at c c. Ifthe paddles and shaft, operated by the crunk C. L is a. stuing-box around theApaddle-shaft. D, the plug, :1t which the alkali is put in. E is n three-way plug, through which gas passes to the gauge, the acid-chamber, and to the fountuins, for use. The gauge may be placed in any convenient manner, and be of any common construction. F, the plug ut which the mixture is drawn oit" when exhausted. F2 are rockers, on which lthe generator stands. G are latches on the rockers, to keep the generator in an upright position when in use. H are knobs on the bottom of the rockers, te prevent the generator tipping forwards. H2 are also knobs on the bottom of the rockers, for steps, when the generator is tilted beek when not in use. I is a coupling-joint, to fasten the acid-chamber K to the top of A. Lis a plug, at which the acid is put in. M is a nipple7 through which gas is passed to equalize the pressure between A and K. N is a. lever, with which the leaden lplug O is raised to permit ncid to pass to A, through the leaden pipe I?. V is the stuffing-box, around the stein of plug O. It is the support under the acid-chamber K. The acid-chamber K is constructed of lead pipe, of suitable diameter and thickness, (new used four-inch diameter and one-quarter inch thick,) of any required length, (the valves, und fittings, and connection being near to one end,) and strengthened by the metal bands a [L a, und is placed at right angleswitlrA. l

To operate the apparatus, A is lled, say, two-thirds full, (tothe line W,) with the proper alkali. K is lled, say, to the dotted line y, with sulphurie acid, which will be about three-fourths full. Reise the lever N, and acid falls into A. Turn the crank C, and gus will be generated. After using, raise the latches G, and let the whole tip back and rest on the knobs H2. -The acid will retire to the then lowcrend of K, thc top forming the dotted line Z, leaving the valve bare or uncovered, so 'that no leuk ot' acid can occur in case the valve should be out of order or imperfect, which it is likely to soon become from the grit which so often accompanies the acid getting into it from the-clay that is used in stopping the cai-boys. Q is a leuden strainer across K, to prevent as much as possible such grit from getting to the valve. o o arebrace's to strengthen the flanges, to prevent breaking as they are being fastened together with the bolts.

What I clim as my invention, 'and desire to secure by Letters Potent, is 1. Constructing the acid-chamber K in such form that when combined with the body of the generator, and charged for use, and tilted bock, thencid in'the chamber will recede or iiow buck from the valve, substantially was set forth.

. Supplying strainersfo the inside of acid-ehuinbers of gas-generators, for the purpose described.

. The 'application of enamel or porcelain lining to the alkali-chamber or body of gas-generators.

. The application of the rockers F2 to gas-generators, as described.

Tilting gus-generators, for the purpose set forth.

(i. Providing gas-generators or fountains, constructed et` cast iron, with the braces o 0 to strengthen the JOHN D. LYNDE.
